With so much conflicting data, with the ever-changing field of nutritional science, and the never-ending stream of advice from well-meaning overnight health gurus, it’s difficult to discern fact from fiction. Seemingly overnight, new trends gain momentum while the old ways are critiqued.

From my personal and professional experience, all forms of evidence behind nutritional advice should be taken with a grain of salt. While the most valued clinical evidence is considered to be from large, randomized double-blind and placebo-controlled trials (RCT’s), even this data often comes with nuances and biases. Conversely, millennia of anthropological data aren’t nearly as valued when discerning types of diet (also intricately tied to lifestyle, it should be noted) and outcomes.
